Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) is the communications domain for
each Wireless Access Point. For wireless PCs that do not need to
support roaming, set the domain identifier (SSID) for the wireless
card to the BSS ID of the Access Point to which you want to
connect. Check with your administrator for the BSS ID of the
access point or bridge to which he wants you to connect.
A wireless infrastructure can also support roaming for mobile
workers. More than one access point can be configured to create
an Extended Service Set (ESS). By placing the access points so that
a continuous coverage area is created, wireless users within this
ESS can roam freely. All SMC wireless network cards and adapters
and SMC2755W Wireless Access Point within a specific ESS must
be configured with the same SSID.
